AliveCor makes consumer and clinical ECG tools. The KardiaMobile devices are small sensors that you touch with your fingers while a phone app records a single-lead or multi-lead electrocardiogram. The app uses algorithms cleared by regulators in many regions to say whether the rhythm looks normal, shows atrial fibrillation, or is unclassified.
Records can be saved, shared with a doctor, and compared over time. People with palpitations or a history of arrhythmia use it to capture an episode as it happens, and clinicians use it to monitor patients remotely. The company also offers a subscription that adds more analysis, reports, and access to cardiologist review.
The devices detect certain rhythm problems, not heart attacks or all heart disease, and a normal reading does not rule out a problem. Anyone with chest pain or severe symptoms should seek emergency care. Alternatives include Apple Watch ECG, Withings, Omron, and Samsung Galaxy Watch. AliveCor suits people managing known rhythm conditions with their doctor.
